Title: Improvements relating to the catalytic reforming of petroleum hydrocarbons
IPC: C10L1/06
Filed: 1956-04-16
Abstract: The octane number of a catalytic reformate or portion thereof is increased by contacting it with a dehydrogenation and dehydrocyclization catalyst at elevated temperature and not more than 50 p.s.i.g., in the absence of hydrogen either extraneously added or recycle.  A platinum reformate is the preferred starting material, and a lower-boiling fraction is preferred, which fraction after treatment may be blended back with the high-boiling fraction; such a blend may be less volatile than the original reformate and the volatility may be increased by adding to the fraction to be treated material boiling below the initial boiling point of the reformate, or the treated fraction and higher boiling fraction blended in proportions to give adequate volatility, T.E.L. being added to maintain the octane number, or the end boiling point of the lower-boiling fraction may be adjusted to exclude toluene-forming components.  The catalyst is preferably a chromia-alumina containing 5-25% chromium oxide, 0.1-5% alkali metal (as oxide) 0.1-5% rare earth metal (as oxide) preferably cerium and the balance alumina. Pressures below atmospheric may be used but atmospheric is preferred, temperatures of 450-580 DEG  C. and space velocities of 0.1-1 vol./vol./hr. may be used.  Fixed, fluidized or moving bed techniques are operable and the catalyst is readily regenerated conventionally. Hydrogen gas is removed as by-product.  Examples are given of the treatment at atmospheric pressure of (1) a light platformate boiling 34-108 DEG  C. at 530 DEG  C. and 0.2 vol./vol./hr; (2) a light platformate boiling 42-110 DEG  C. at 492 DEG  C. and 0.2 vol./vol./hr., 521 DEG  C. and 0.21 vol./vol./hr. and 549 DEG  C. and 0.19 vol./vol./hr., the products being blended with a heavy platformate boiling 125-214 DEG  C.; (3) a total platformate boiling 92-177 DEG  C. at 525 DEG  C. and 0.2 vol./vol./hr.; (4) a heavy platformate boiling 114-213 DEG  C. as in (3).  Examples are also given showing the effect of varying temperature, alkali metal promoter and pressure and comparing treating a light reformate and blending with the heavy reformate to treating the whole reformate. The catalyst in each case is promoted chromia-alumina as described.

Class 38(5) The co-operating contacts 48, 100 are completely surrounded by and enclosed in an exhausted pressure-responsive capsule. 81 which is mounted resiliently in a housing 5 connected via a pipe 7<SP>1</SP> to the pressure to which the switch is to respond. The membranes 80, 84 of the capsule 81 are connected over blocks 50, 90 to capsules 71, 110, the outer ends of which are connected to the casing, these capsules acting to neutralize the effects of vibration and acceleration on the contacts. Capillary tubes 152, 153 connecting the interior and exterior of capsules 71, 110, ensure that, with a sudden change of pressure in the housing 5, the pressure in the capsules 71, 110, is equalized only slowly, so that the contacts are not separated by the response of .capsule 81 unless the pressure change persists. These tubes 152, 153 may be omitted if desired and the capsules 71, 110 may be replaced by springs. The upper membrane 115 of capsule 110 is connected to an adjusting screw 132 so that the operating pressure may be varied. In a modification (not shown) the interiors of capsules 71, 110 are connected to a separate pressure inlet so that the switch acts differentially.

Abstract: <PICT:0948647/C1/1> <PICT:0948647/C1/2> <PICT:0948647/C1/3> A process for producing a sintered body from a composition comprising finely divided glass, preferably soft lead glass, and more than 8% but less than 12% by weight finely divided aluminium oxide, includes the steps of placing the composition in a shaped pressure mould, subjecting the mould to at least one pressing operation and to at least one sintering operation. The glass/alumina composition is preferably of uniform particle size and usefully 10 microns. Sintering may take place in a nitrogen atmosphere or a reducing flame at about 1200 DEG C., after which the mould is immediately pressed for a second time. The invention also includes attaching metal parts to the sintered body, wherein after the first pressing and sintering the formed body is immersed in a borax solution, dried and re-sintered.  The metal inserts which may be wires are preferably copper coated or copper foil inserts may be used between the metal and the glass.  The second sintering may be effected by radio-frequency heating.  The metal to glass seal produced is claimed to be vacuum tight and employs alloys of iron, chromium and/or nickel.  The order of assembly and dipping in borax may be raised. The invention is particularly described with reference to the vacuum tube components illustrated.

Class 120 (2). A method of lubricating the ring and traveller in a wet ring spinning or twisting frame comprises applying to the fibres to be spun an oil and/or wetting agent, which together with the water in the yarn constitutes a lubricating liquid which is automatically applied to the ring and traveller by the passage of the yarn through the traveller, the oil and/or wetting agent being applied to the fibres prior to reaching the drawing stage in the spinning and twisting frame and prior to or subsequent to passing through the macerating trough. The centrifugal action upon liquid remaining in the yarn as the bobbin is wound is stated to assist the lubricating process. The oil and/or wetting agent may be sprayed or caused to drip on to the fibres. Examples given of suitable lubricants are lime soap base oil and sulphonated sperm oil.
